Engineering Characteristics of Permeability Concrete for Road Pavement by Recycled Aggregates

순환골재 사용에 따른 도로포장용 투수성 콘크리트의 공학적 특성

In this study, the qualitative characteristics of the permeability concrete by the changes in the grading of the recycled aggregates were analyzed and its results are as follows. First, the compressive strength represented the low range of strengths comparing with the typical concrete, and the high compressive strengths were represented as the aggregates with small grading of 2.5mm were used. The bending strengths did not satisfy the targeted range, and the permeability coefficient represented to be good when the aggregates with single grading greater than 5.0mm and the mixed aggregates of 5.0mm with 10.0mm.
